IMPROVEMENT IN HORSE-POWER elle riptnle nimh It in that @letters tantmit mating nrt at tigtr same.

TO ALL WHOM IT'fMAY CONCERN:

Be it known that I, ANDREW SMITH, of Dayton, inr the county of Yam Hill,and State of Oregon, have invented 'a new and useful Improvement inHorsePower; and I do hereby declare that the following'is a full, clear,and exact description thereof, which will enable others skilled in theart to makeand use the same, reference being had to the accompanyingdrawings, forming part of this specification, in which- Figure 1 is aplan or top view of my invention.

Figures 2 and 3 are vertical sections of a portion ofthe same, takenrespectively in the lines :c rv, y y, g. 1.

Similar letters of' reference indicate corresponding parts.

This, invention relates to a new and improved horse-power, in whichbelts-are employed, insteadof gearing, for transmitting the power fromtii' driving-wheel to the shaft from which the power is taken. Theinvention is designed for a portable machine, which may be readily putup and taken down, and readily kept in repair by any person of ordinaryability. l i

In the accompanying sheet of drawings, A represents a suitable frame, inwhich a verticalshaft, a, is rmly secured, having a wheel, B, keyed'-upon it, to'wliich a. sweep, C, is attached, the rim of the wheel Bresting or bea-ring upon anti-friction rollers, b, as shown clearly iniig. 1. i y

D is a driving-belt, which passes around` the wheel B, and is made tohug the periphery of' said wheel by means of twovertical rollers, c c,as indicated by the dotted lines in iig. 1.

This frame A is staked to the ground in any suitable way` v E is aframe, in -which a vertical shaft, d, is tted, and on which a wheel, F,is keycd,'around which the driving-belt D passes. rllhisshaft d isadjustable in thel direction indicated by the arrows 1 1 and2 2, (seeiig;`

L 1,) the bearings e of the shaft d being connected by a bracket, F, inwhich a screw, G, is fitted, and by turning which the bearings may bemoved in the direction of the arrows 1.

The bearings .e are ittcd in slides H H, which are connected by abracket, I, in which a screw, J, is tted, and, by turning this screw,`the bearings may be moved inthe direction indicated by the arrows 2. Bymoving the bearings in the direction indicated by the arrows 1, thedriving-belt D may always Ybe kept at a proper degreeof tension. Y g 1In the frame E there is also iitted a vertical shaft, K, having apulley, L, upon it, and also a wheel, M.

A belt', N, passes around the pulley L, and also around`a wheel, O, inthe shaft d, above wheel F.

By moving theslides H H, through the medium of the screw J, the belt Nmay be tightened and kept at theproper degree of tension.

The horse is attached to the sweep C, and rotates the wheel B, inpassing around frame A., a bridge being l placed over the driving-beltD, for the horse'to walk over. The power is taken from.. the wheel M.

The advantage of this invention consists inthe simplicity of itsconstruction, the moderate costof manufacture, and the facility withwhich it may be kept in repair by any' person of ordinary mechanicalability.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent,-

The shaft d, in the frame E, arranged so as to be capable of beingadjusted in-two different directions by means of the screws J G,connected respectively with the 'slides H and bearings e, as indicatedbythe arrows 1 2, in combination with the frame A, containing thedriving-belt D and rollers c c, and the b elt with the shaft K in frameE, all arranged for joint operation, substantiallyin the manner as andfor the purpose set forth. i

ANDREW SMITH.
